indicates significant between-task differences (P < 0.05). Displacement error was minimal (<3 mm) and consistent between groups, hemispheres and across tasks (P > 0.05). Angle error was somewhat greater during B and B compared to rest and grip (P's < 0.02), but within our targeted range (<5°); no group or hemisphere differences were revealed. CH, contralesional hemisphere; IH, ipsilesional hemisphere; B and B, box and blocks task.
